[Development] Qt Quick emulation layer crashed (1:0)

Hello everybody!!!

I have been testing Qt5.6

of course Beta an RC releases have some bugs as expected.

But in all recent linux releases including the final 5.6.0 release the QML
design view is completely unusable.

Even the most simple qml led to "Qt Quick emulation layer crashed (1:0)"

I have been working in complex QML layouts and *the designer was never
really as useful* as expected. it is very buggy across all releases from it
first appearance.

But now it can't handle even something as simple as this example:

import QtQuick 2.5
import QtQuick.Controls 1.4

ApplicationWindow {
    id: applicationWindow1
    visible: true
    width: 640
    height: 480
    title: qsTr("Testing")

        interval: 1500; running: true; repeat: true
        onTriggered: {

    Rectangle {
        id: testRectangle1
        width: 383
        height: 86
        color: "#c2c2c2"


This code runs ok but can't be edited in design mode because "Qt Quick
emulation layer crashed (1:0)" shows up.

is there a workaround? or some alternative?
